Almost every trip I look at for next year (May/June) has a 'Fare Alert'. Have they stopped Seniors Discounts or is that school holiday time in America ?
They are reducing the senior discount and upping the age to qualify to 65 (there’s a thread discussing these changes)
If there is a saver gate available and you had selected Senior for the discount, it’s letting you know that the saver fare is less than the regular fare minus the discount.
